Description

A kind of equipment water jetting cooler of on billet caster, producing the circle base
The utility model relates to the equipment water jetting cooler in the conticaster, and it is applicable to and produces circular continuous casting billet on billet caster.
Continuous casting process has replaced die casting process and has been widely used in steel mill because of its lumber recovery height, low power consumption and other advantages.Equipment water jetting cooler on the conticaster of production square billet is by being arranged on cooling section I at present AForm with square strand (1) sparge pipe (2) and the water spout (3) on every side of cooling section I, four water spouts (3) are arranged vertically with corresponding four faces of square billet (1) respectively.It is generally acknowledged in the steel mill at home and abroad and on billet caster, square billet can only be produced and can not produce circular continuous casting billet that this is because the strand arc radius of billet caster is less.For example a kind of strand arc radius of billet caster only is R 2=5250mm, and the strand arc radius of circular conticaster is generally all more than 10000mm.When molten steel forms the shell base in the crystallizer of production round billet continuous casting machine, after pulling out crystallizer under the driving of straightening machine (8), required cooling condition is compared with the cooling condition of producing square billet on billet caster, needs the more even cool time of length.Strand arc radius just because of billet caster is little, can not satisfy the needed cooling condition of production circle base, so production circle base is considered to be impossible realization on existing billet caster.
The purpose of this utility model is a kind of equipment water jetting cooler that can produce the circle base on billet caster of design, satisfies market to justifying the demand of base with the function of " dual-use ".
Structure of the present utility model is to realize like this.
The equipment water jetting cooler of producing the circle base on billet caster is by being arranged on cooling section I AForm with strand sparge pipe and the water spout on every side of cooling section I, characteristics are along the continuous water spray cooling section II that sets up of the every stream of cooling section I; Each cooling section is provided with four sparge pipes, and four water spouts are arranged on its cross section, the water spout phase alternate angle α on the neighbouring section=45 °, and water spout is a upper tightly lower sparse along the spacing of strand traffic direction setting.
With next embodiment and accompanying drawing the utility model is described in detail below.
Fig. 1 is the cross-sectional configuration schematic diagram of billet caster equipment water jetting cooler.
Fig. 2 is a main TV structure schematic diagram of the present utility model.
Fig. 3 is the structural representation of the utility model along the A among Fig. 2-A section.
Fig. 4 is the structural representation [shedding water nozzle (3) or (4)] of sparge pipe of the present utility model (6).
Fig. 5 is the structural representation of water spout of the present utility model (3) or (4).
The equipment water jetting cooler of producing the circle base on billet caster is by being arranged on cooling section I AForm with round strand (5) sparge pipe (6) on every side of cooling section I, be characterized in along the continuous water spray cooling section II that sets up of the every stream of cooling section I; Cooling section I A, cooling section I is provided with identical four sparge pipes (6) with cooling section II, its cross section is provided with four water spouts (4), water spout on the neighbouring cross section (3) and water spout (4) be alternate angle α=45 ° mutually, they on sparge pipe in the shape of a spiral wire shaped arrange.Round strand (5) on each cooling section sparge pipe (6) on every side is respectively an outer arc sparge pipe, an inner arc sparge pipe and two corresponding side arc sparge pipes, and their pairing outer arc radiuses, inner arc radius and side arc radius are respectively R 3=5450mm; R 1=4900mm; R 2=5175mm.Because R 1, R 2And R 3Numerically be close, so, can be considered as the curvature of the sparge pipe (6) on their pairing inner arcs, side arc and the outer arc approximate identically, sparge pipe is also approximate identical.Angle β=75 between neighbouring two water spouts of same sparge pipe (6) (3) and (4) °.Water spout is a upper tightly lower sparse along the mutual spacing of circular strand traffic direction setting.
Water spout along the spacing of circle base (5) traffic direction setting is: L 0=30mm; L A1=165mm; L A2=165mm; L A3=190mm; L A4=190mm; L A5=220mm; L A6=220mm; L AI=240mm; L AI1=260mm; L AI2=290mm; L AI3=310mm; L AI4=350mm; L AI5=400mm; L AI6=460mm; L III=520mm; L II1=570mm; L II2=570mm; L II3=570mm; L II0=33.8mm; The baseplane Q of crystallizer (7) and cooling section I ABeginning plane P and the central angle alpha formed of the center of circle O of casting machine arc 0=4 °; Cooling section I APairing central angle alpha A=13.3 °, the pairing central angle alpha of cooling section I I=23.6 °, the pairing central angle alpha of cooling section II II=23.6 °.
Cooling section I of the present utility model APreceding four rows' water spouts adopt BD5 type structures; Cooling section I ABack three rows and the water spout of cooling section I, cooling section II employing BD3 type structure.The structure of so-called BD5 type water spout be water under high pressure can be along the direction of arrow from water spout the tangential direction in (3) or (4) cross section enter, water under high pressure forms the rotary water current that advances at water spout inner chamber (9), form the strong aproll stream that revolves through the diminishing spout of bore (10) and penetrate, splash is to the surface of circle strand (5).The structure of the structure of BD3 type water spout and BD5 type water spout is basic identical, and their difference is varying in size of spout (10), and the spout (10) of BD3 type water spout is slightly littler than the spout of BD5 type water spout.
Of the present utility model simple in structure, it can reach the technical quality requirement of producing the circle base on billet caster through production practices, has realized " dual-use " and has satisfied the needs of market to circular continuous casting billet, and brought favorable economic benefit to enterprise.
